So you really helped me and calmed me down! thanks guys. But let me know just a few things? How would be the perfect way to learn this scales stuff from my level, my teacher said the best would be to learn the fretboard with each tone by heart, but that would be quite hard, but i would be ready to do this. So but when i learned this what should i do know, if i know the fretboard by heart? Another question: What are the other main important things that you should learn very well to get a good guitarist, because i don´t know if that what i practice is right or the best( I would also be ready to practice 7 hours a day. And the last question: I want to know if it is good that i can play the "one" solo, majority of sad but true, and justice and master of puppets solo by metallica after half a year playing the guitar and 3 months playing the e guitar? Were you better when you were in my age(15) or at my practicing time? Am i at a good way?
I know these are quite a lot of questions, but althuogh try to answer as much as possible.
